Synonym



A synonym is a word, morpheme, or phrase that means precisely or nearly the same as another word, morpheme, or phrase in a given language. For example, in the English language, the words begin, start, commence, and initiate are all synonyms of one another: they are synonymous. The standard test for synonymy is substitution: one form can be replaced by another in a sentence without changing its meaning. Words may often be synonymous in only one particular sense: for example, long and extended in the context long time or extended time are synonymous, but long cannot be used in the phrase extended family. Synonyms with exactly the same meaning share a seme or denotational sememe, whereas those with inexactly similar meanings share a broader denotational or connotational sememe and thus overlap within a semantic field. The former are sometimes called cognitive synonyms and the latter, near-synonyms, plesionyms or poecilonyms.

Lexicography
Some lexicographers claim that no synonyms have exactly the same meaning (in all contexts or social levels of language) because etymology, orthography, phonic qualities, connotations, ambiguous meanings, usage, and so on make them unique. Different words that are similar in meaning usually differ for a reason: feline is more formal than cat; long and extended are only synonyms in one usage and not in others (for example, a long arm is not the same as an extended arm). Synonyms are also a source of euphemisms.

Metonymy can sometimes be a form of synonymy: the White House is used as a synonym of the administration in referring to the U.S. executive branch under a specific president. Thus, a metonym is a type of synonym, and the word metonym is a hyponym of the word synonym.

The analysis of synonymy, polysemy, hyponymy, and hypernymy is inherent to taxonomy and ontology in the information science senses of those terms. It has applications in pedagogy and machine learning, because they rely on word-sense disambiguation.

Etymology
The word is borrowed from Latin synōnymum, in turn borrowed from Ancient Greek ' (συνώνυμον), composed of ' (σύν 'together, similar, alike') and -- (-ωνυμ-), a form of  (ὄνομα 'name').

Uses
Synonyms often express a nuance of meaning or are used in different registers of speech or writing.

Various technical domains may employ synonyms to convey precise technical nuances.

Some writers avoid repeating the same word in close proximity, and prefer to use synonyms: this is called elegant variation. Many modern style guides criticize this.

Examples
Synonyms can be any part of speech, as long as both words belong to the same part of speech. Examples:


 * noun: drink and beverage
 * verb: buy and purchase
 * adjective: big and large
 * adverb: quickly and speedily
 * preposition: on and upon
 * Abandon: Forsake
 * Abdicate: Renounce
 * Accessible: Approachable
 * Acknowledge: Admit
 * Adjacent: Next
 * Adopt: Embrace

Synonyms are defined with respect to certain senses of words: pupil as the aperture in the iris of the eye is not synonymous with student. Similarly, he expired means the same as he died, yet my passport has expired cannot be replaced by my passport has died.

A thesaurus or synonym dictionary lists similar or related words; these are often, but not always, synonyms.
